Oracle has decided to weigh in because Lodsys “has repeatedly threatened numerous Oracle customers” such as Walgreens over the use of a web-chat feature Lodsys claims to own. Oracle is asking the court to declare that the four patents Lodsys is using to bully its customers are not new inventions. The patents, including US Patent 5,999,908 (“customer based design module”), came to prominence last year when Lodsys used them to sue Best Buy, Adidas and others.
